Vodafone connect router DHCP settings

[mattman]

I have posted this into off topic as I can not see any reference to Vodafone Home phone and Broadband.

I have install the router and all is working but there one thing that is missing from the setting of the VDSL router that being a function to turn off DHCP, I have for the pasted 10 year had my own network running at home with a fully working server that is my DHCP & DNS server but for the first time in history I have just sign up for 18 month and got a bloody router that has no function in the GUI settings pages to turn OFF the DHCP server. So for now I will have to wait for 18 months before I can change ISP. thanks vodafone tech team for missing this one. If there is anyone out there that can offer me a firmware update to give me the function to turn OFF DHCP then please post it.

I'd be careful with buying 2nd hand Vodafone routers from eBay.

I've been informed by Vodafone CS that the serial number of the router is tied to your broadband account, and indeed have had to give them the serial number over the phone to verify that I was actually using the 'correct' one.

So, unless you can hack the S/N, you'll probably be just wasting your time and money.

In my particular case, Vodafone actually insisted on sending me a different router rather than take the easy option and just enter the old router S/N into their system. But they seem mental like that with a lot of things they do.

I think the idea is to obtain a spare VF router in order to try some invasive tests to see if the config can be extracted in an unencrypted form, not to actually connect to the VF network.

For example, a spare could be experimented on for soldering headers to unpopulated parts of the motherboard to attempt to find a serial console or diagnostic port.

I don't inted to use it with the Voda service. I want to use it as playground device to figure out the way how the router obtains the password, stores and/or decrypts it. 

if that fails, it would be still nice to figure out how to use othe options of the hardware. it would be nice to get ethernet WAN anabled and FXS ports as well.

Ok, that's cool

Are the passwords random strings of chars?

If not, I assume you've tried the reverse MD5 / SHA-1 lookups? Nothing to say it would be as simple as that anyway. AES and salt etc. or whatever...urghhh.

If people that previously got told them when they requested - and still had the hashes available?

To be honest I'm not sure. the new firmware encypts the whole config file. 

[dawnydoodles]

Not easy to decrypt at all then, in that case.

Sadly, I lack the skills required, but reading around suggests that a dump of the firmware would be step 1.  Once that's out in the wild, there's smart people out there who tear those firmwares apart for fun.

If the config is encrypted, then the router's furmware contains the encryption key.  Once that's been extracted, the configs can be decrypted... and we're away!

[csiwek]

these days firmwares are also being encrypted hut it hard to say what is actually happening there. The first step is to get the serial console access I was unable to locate that yet.

btw, I've started a thread on kitz. co . uk some time ago. If anyone would like to participate, please do.

Signed up. Speak to you on there.

If you can get the Ethernet WAN enabled, you're almost there.. You can plug the Ethernet WAN side into your laptop and sniff using Wireshark. The DHCP broadcast may include certain packets with your login details in them.
